Obscuring Haze card art
Obscuring Haze blanks an entire combat step for free if you control no nonland permanents other than green ones — a one-sided Fog that costs nothing in the right shell. Thantis, the Warweaver runs it to survive the forced-attack chaos it creates, and Anzrag, the Quake-Mole uses it to let its board swing in uncontested while leaving blockers flat-footed.

Best Commanders

Commanders with the highest synergy

01
Thantis, the Warweaver

Thantis, the Warweaver

46.8% of decks · synergy 0.44

Thantis, the Warweaver forces every creature on the table to attack every turn, which means it's getting hit back — Obscuring Haze cancels that incoming damage for free, letting the attrition engine run without costing Thantis its life total.

02
Anzrag, the Quake-Mole

Anzrag, the Quake-Mole

39.3% of decks · synergy 0.35

Anzrag, the Quake-Mole wants to trigger whenever it's blocked, and Obscuring Haze clears the way by wiping out an opponent's entire blocking step, keeping Anzrag swinging and triggering without the usual combat risk.

03
Carth the Lion

Carth the Lion

36.5% of decks · synergy 0.34

Carth the Lion runs a planeswalker-heavy gameplan that benefits enormously from protecting its board state; Obscuring Haze buys a free turn of safety, letting planeswalker loyalty tick up without opponents threatening via combat.

04
The Cabbage Merchant

The Cabbage Merchant

35.8% of decks · synergy 0.28

The Cabbage Merchant cares about keeping creatures alive to exploit counters and value triggers, and Obscuring Haze's free nullification of a combat phase does exactly that without spending a mana the deck could spend elsewhere.

05
Kathril, Aspect Warper

Kathril, Aspect Warper

28.4% of decks · synergy 0.27

Kathril, Aspect Warper builds a single enormous keyword-stacked threat that becomes the primary win condition, and Obscuring Haze protects that threat — and its pilot — from a retaliatory attack for nothing if the board is green-clean.

Obscuring Haze is where it belongs: Commander. The "no nonland permanents other than green" clause is easy to satisfy in a mono-green or heavily green deck, and a free Fog in a four-player game is worth substantially more than a Fog you paid two mana for — one card answers three opponents simultaneously. In Legacy and Vintage it's technically legal but sees no meaningful play; the formats move too fast and too linearly for a conditional combat trick to matter. Oathbreaker is the only other format where it has a plausible home, again only in green-heavy lists where the condition is reliably met.

Budget Alternatives

Cheaper options that do most of the same work

Fog and Tangle are the closest functional replacements at under $0.50 each — they stop combat just as cleanly, but you're paying one or two mana for the effect instead of zero, which matters most in the turn-three and turn-four windows where Obscuring Haze is free. Defend the Hearth and Haze of Pollen cover the same role at negligible cost and are worth considering in lists that can't consistently satisfy the all-green-permanents condition, though none of them replicate the zero-mana upside that makes Obscuring Haze the first choice.

Price Context

Current price

$5.34 mid tier

At $5.34, Obscuring Haze sits in the mid tier — reasonable for a card with a genuinely unique rate, but only if your deck reliably meets the condition. It's a one-card slot that earns its price in the right shell and is wasted money in any list running meaningful artifacts or nongreen permanents.
